The return of bloody conflict (3)
I believe the answer is:
war
'conflict' is the definition.
(war is a kind of conflict)
'the return of bloody' is the wordplay.
'the return of' is a reversal indicator.
'bloody' becomes 'raw' (as in raw meat).
'raw' back-to-front is 'WAR'.
(Other definitions for war that I've seen before include "Open hostility" , "State of armed struggle" , "Fight" , "Armed hostility" , "Strife" .)
